I think, basically, passing though the massive gravity plain emanating from the galaxy's central super massive black hole, as we will on 21/23 -12 -2012, may well be enough to physically knock the whole planet off it's current spinning axis.
Like a spinning top, if it bumps into something it no longer spins true and wobbles on a random new axis... unlike a spinning top, which then stops and falls, the Earth once it's taken this gravity impact causing the new random wobble, would carry on moving out of the galaxy's gravity plain.
The planet then has time to settle into it's new rotational axis.
All well and good. So what effect does this have.
Well, one from what I can understand.
The Earth's tectonic plates are floating on the mantle/core, they are not attached, this would allow freedom of moment.
The planet is revolving incredibly fast, this actually has the effect of shaping the planet into a slightly squashed sphere, thicker at the equator due to centrifugal force of rotation.
OK, so if the planet spins on a new rotational axis, the old locations of the poles will push back up and the new pole locations will pull down. Equally, the old equator will drop down and the new equator will be forced out, due to the centrifugal force of rotation.
This equals, in short, the planet would be fucked and we are all gonna snuff it in massive floods and earthquakes... THE END!
The Boxing Day earthquake 2004 was about 9.3 and only 30km deep, one of the most powerful quakes in recorded history, lasting only about ten minutes and causing quakes as far away as Alaska, that was from a plate slip measuring 1600km long and shifting up only about 20m. Can you image the force released from the whole planet reconfiguring it's shape!
On a lighter note, this seems to have happened a number of times in Earth's 4 billion year old history and we, Earth, is still here. It may happen every time we cross the galaxy's gravity plain, once every few tens of thousands of years, yet there is still life here on Earth.
I'm seeing a degree of frightening and understandable, rational science here, just dress up in a lot of frightening superstition and doom saying.
I've decided to hide under the bed, which is of course the safest place for us pups in times of distress and fear.
